Name of Session: Flower Power (or Sex Under the Microscope)

Session Leaders:
Joy, Sally, and Ellie

Length of Session:
Part 1 (Day 3): 1 hour, 30 minutes

Learning Goals for DVI Fellows:
The Learner will:

  • Understand how magnifying glasses and microscopes can be used to visualize details that are otherwise too small for the naked eye.
  • Explore the reproductive structures of flowering plants at the microscopic level and develop an understanding of how fertilization and embryogenesis occur.
  • Demonstrate the mastery of learned concepts through the creation of a visual presentation.

Summary of Activities:
Materials Required:
Plastic magnifying glasses
Word cards
QX5 Microscopes and Laptops
Computer with Projector
Fresh Lilies and other flowers

Session Overview:
Engage
  • Fellows will be asked questions regarding objects around them. Can they see every detail of the world? What could they use to help them see things that are too small to be seen with the naked eye?
  • Fellows will be given magnifying glasses to help them read name cards with very small words on them.

Explore
  • Fellows will dissect seeds and flowers, comparing the different structures using the QX5 microscopes, and recording their observations using the digital image capture feature.
  • Fellows will use the software to annotate their photos, and they will be shown how to export the photos as thumbnail jpeg images.

Explain
  • Fellows will identify flower structures. The functions of the various structures will be discussed and related to fruit anatomy.

Elaborate

  • Fellows will develop posters to present their data (photos), linking the structural information that they observed to the functional information that was discussed, such as how pollination occurs, how seeds disperse, how seed-dispersal mechanisms contribute to a plant’s survival.
